Analysis of the Mechanical and Biological Effects of 3D Printing Techniques in the Design and Construction of Dental Restorative Prostheses: A Comparative Study between Traditional Methods and Advanced Digital Technologies

This study comprehensively evaluates the mechanical and organic performance of 3D- published dental prostheses in comparison to standard techniques. A laboratory- primarily based comparative layout assessed compressive energy, flexural staying power, floor roughness, cytocompatibility, and bacterial adhesion throughout 20 samples (10 traditional, 10 3D-printed). Results revealed that 3D-published prostheses exhibited superior precision (surface roughness: 0.35 vs. 0.55 µm; p < 0.001), fatigue resistance (62,100 vs. 52,300 cycles; p < 0.001), and biocompatibility (mobile viability: 93.5% vs. 86.2%; p = 0.007). However, fabric-dependent limitations were obvious, with photopolymer resins displaying decrease fracture resistance than PEEK or cobalt- chrome alloys. Bacterial adhesion reduced through 32% on 3D-published surfaces (p < 0.001), underscoring their medical potential for infection-susceptible instances. The have a look at concludes that 3D printing gives a possible opportunity for precision- driven applications but necessitates fabric improvements for high-load scenarios. Future studies should discover complex geometries and lengthy-term in vivo performance to optimize scientific adoption.
